Study on the electron spin state of La_2@C_(80) anion

摘要

Spectroscopic study on fullerenes offers the likely playground for the discussion of molecular symmetry in 3-D fashion.And a multi-metallofullerene ( a fullerene with a metal cluster inside the hollow spherical carbon cage ) is an interest in terms of the chemical trap of an active metal cluster in stable form under the atmosphere.Lanthanum monomers with various C_n cages (La@C_n) and an anion form of a lanthanum dimer with C_(80) cage (La_2@C_(80)~-) were measured by an ESR spectrometer.
